I do not see any ip address configured on the Internet facing interface (ge-0/0/4.0) and there is no default route configured towards ISP.
Please follow below mnetioned steps:
1. Configure ip address on ge-0/0/4
set interfaces ge-0/0/4 unit 0 family inet address xx.xx.xx.xx/xx
2. configure default route towards ISP ip
set routing-options static route 0.0.0.0/0 next-hop <xx.xx.xx.xx>
3. Commit the changes
commit and-quit
4. Check the reachability from SRX
ping <ISP ip / next-hop ip>
ping 8.8.8.8
traceroute 8.8.8.8 no-resolve
5. If reachability working fine from SRX, try to access internet from your LAN
